Jiraiya

Jiraiya is one of Konohagakure's Legendary Sannin in Naruto Shippuden and the teacher of Naruto Uzumaki. A wandering ninja and novelist, he investigates Akatsuki while carrying the hope that one of his students may bring peace.

Jiraiya as one of the Legendary Sannin

Boisterous, eccentric, and openly lecherous, Jiraiya also possesses deep loyalty and insight. Failures involving Orochimaru, Tsunade, and former students make him determined to guide Naruto without controlling his choices.

Toad Sage techniques and the legacy of his students

Jiraiya uses toad summoning, fire and earth techniques, barrier ninjutsu, and Sage Mode. Training Minato, Nagato, and Naruto links him to multiple generations, and his final investigation of Pain provides crucial information at the cost of his life.
